Title: Loudspeaker
Inventor: OONO AKIRA
IPC: H04R7/02
Filed: 1982-02-01
Abstract: PURPOSE:To eliminate influence of humidity, and also to obtain an ideal attenuation characteristic, by using a super-elastic alloy as a base material of a diaphragm. CONSTITUTION:Such alloys as Ti-Ni, Ti-Ni-X (X: Cu, Fe, Cr, etc.), Cu-Zn-Al, etc. are called shape memory alloys. These alloys become a super-elastic alloy showing a deformation movement like rubber, by setting a inverse transformation end temperature to a room temperature or below. That is to say, a large elastic strain area is realized, and since elastic hysteresis of a base material is large, an attenuation characteristic against vibration is excellent. Accordingly, if it is used for a diaphragm 6 of a loudspeaker, generation of divided vibration is reduced remarkably, and it is possible to improve a frequency charactoeristic at the time of large amplitude or in intermediate and high temperature areas.

Title: Method for decision of visibility
Inventor: HIYUBERUTO GURAMURINKU
IPC: G01S17/931
Filed: 1994-01-14
Abstract: PURPOSE: To determine visibility by a single transceiver by interpreting a large increase in intensity in a range that a backward scattering signal exists more than an approximate standard curve of an expected backward scattering signal as an obstacle, and finding a distance from scanning time of an increased backward scattering signal. CONSTITUTION: A transceiver 21 transmits a light pulse 19. A slight part of the light pulse is directly introduced to a receiver 22, and the other light measured by the receiver 22 reaches there by backward scattering. The expected passing of a backward scattering signal is obtained by inluding an increase 15, and the increase 15 is generated by whether the light pulse is reflected or scattered by an obstacle 29. A distance between the obstacle 29 and a traveling car is calculated by a prescribed expression from traveling time (tH) and light speed of the light reflected by the obstacle 29. The calculated distance is displayed for a driver. Relative speed between the traveling car and the obstacle 29 is inferred from a change in a distance between the obstacle 29 and the traveling car during continuous several time measurements.  This measure becomes important when the obstacle 29 exists before the traveling car in a visibility range.

Title: Blowing method of dephosphorizer to bottom blowing converter
Inventor: UMADA HAJIME
IPC: C21C5/34
Filed: 1979-02-14
Abstract: PURPOSE:To achieve dephosphorization effect with less lime use amount and reduce the amount of slag formation by adding part of quicklime for desulfurization at the time when the C content of the bath has decreased at the end period of blowing, at the bottom blowing converter operation. CONSTITUTION:In producing steel by oxidation refining molten iron in the bottom blowing converter, quicklime powder as a slag forming material is blown together with oxygen for refining through the bottom tuyere. Since the FeO formed by the oxygen blown near the tuyere is used preferentially for oxidation decarbonation reaction of C in the bath at the initial period of refining, the oxidation of P in the bath by FeO begins on a full scale from about final 20% of the time when the decarbonation reaction progresses and has entered low carbon region. Hence, at this timing, i.e., at the time when the greater part of the decarbonization reaction ends upon lapse of 80% of blowing time, CaO as flux for dephosphorization slag is blown 4-20kg per ton of molten steel together with oxygen through the bottom tuyere. Slag amount can be less, hence the losses of FeO into the slag are reduced.

Title: Treatment of measuring data of space filter
Inventor: SUZUKI MASATOSHI
IPC: G01P3/54
Filed: 1982-02-01
Abstract: PURPOSE:To measure the speed of a travelling body precisely and highly accurately by selecting a space filter output data group of which period data strings are stable and extracting effective data in the selected data group to calculate the speed. CONSTITUTION:Output signals based upon the detection of reflected light from a car or the like through two system space filters 11, 12 are converted into pulse signals having pulse width corresponding to the period of pulsation by AGC circuits 6 and binary-coding circuits 61 and used as pulse signal strings for one car. The signal strings are counted and converted into period data strings by counters 62 and the converted data strings are successively stored in a microcomputer 60. Since a stable data group when a single edge part of the car is projected into the filter field is selected, only the effective data in the selected data group can be extracted and averaged. The speed is calculated from the  mean value, so that the speed of the travelling body can be measured precisely  and highly accurately.

Title: Corrosionproof heat exchanger part and manufacture thereof
Inventor: AKACHI HISATERU
IPC: B21D53/08
Filed: 1984-01-31
Abstract: PURPOSE:To prevent contact heat resistivity due to corrosion from increasing by filling a mutual very small gap between an insertion part of each of fins and an external circumferential wall surface of a heat transfer tube, by bonding mutually the insertion part and the wall surface by making use of an adhesive agent which is favorable in thermal conductivity and is wealthy in corrosion resistance. CONSTITUTION:Simultaneouly with an insertion of a sheet of a fin 2 on an end of a heat tranfer tube 1 of a fin group insertion type heat exchanger, uncured paint 7 of a corrosionproof adhesive agent, whose thermal conductivity is favorable, is applied by a predetermined quantity to a part closer to the fin 2 inserted temporarily than a position where the fin is fixed. Then the fin 2 is made to slide in the direction of an arrow and fixed by making the fin 2 move to a position where the fin 2 is to be fixed. The paint intrudes into a space between a burring part and an external circumferential wall surface through wedge effect based on a slide of the fin 2, a very small quantity of which is left behind on the wall surface, coated over the external circumference of the heat transfer tube in a thin film and a corrosionproof thin film 5 is formed. In this instance, a very small gap between the burring part and the external circumferential wall surface is filled completely. Then the adhesive agent is made to cure. As for the adhesive agent, an epoxy adhesive agent to be obtaned by mixing dust-size particles of metals such as aluminum, copper, silver and beryllia or oxidized metals of them is preferable. With this construction, fin efficiency is improved and corrosion resistance becomes favorable, through which slackness based on external force does not occur. As the adhesiveness is of a low-temperature adhesiveness this is adoptable to a heat pipe also.

IPC: H01R13/03
Filed: 1993-02-02
Abstract: PURPOSE:To save an amount of a metal layer fixed to the surface of a contact, and shorten a time to fabricate mounting parts. CONSTITUTION:At a process prior to a press punching process, a metal layer 13 is fastened to a hoop material at the predetermined position corresponding to the connecting section 1a of a contact 1 for electrical connection to a mating part. At the press punching process, the cutting plane of the connecting section 1a is covered with the metal layer 13. Furthermore, as a result of a drawing process, the metal layer 13 on the connecting section 13 expands and adheres to the cutting plane as well, due to the ductility thereof. According to this construction, the metal layer 13 can be formed only on the connecting section 1a of the contact 1, and the consumption of plating material can be saved. Also, a plating process between pressing and assembly processes can be eliminated. Thus, both of the processes become consecutive and a fabrication time for mounting parts can be shortened.

Title: Method for maintenance of electron beam exposure device
Inventor: OSADA TOSHIHIKO
IPC: H01J37/141
Filed: 1979-02-13
Abstract: PURPOSE:To prevent an electically poor conducting film from being formed in a narrow space by covering the surface of a narrow space which is to become an electron beam path by non-magnetic metal foil. CONSTITUTION:The inner walls of small holes 11a and 11a' of pole pieces 11 and 11' made of pure iron are fitted with hollow cylinder 14, made of non-magnetic metal, such as aluminum foil, and having diameter smaller than those of small holes 11a and 11a'. Subsequently, the upper and lower ends are spread outside and these are covered by cylinder 14. As a result, an electrically poor conducting film produced by the decomposition of lubricant vapor by the electron beam does not directly stick to the inner walls of small holes 11a and 11a' but it is formed on the inner surface of cylinder 14. Consequently, at the cleaning time, the used cylinder 14 is taken out by means of tweezers and it is replaced by new cylinder 14.
